1、电线电缆材料用量计算公式铜的重量习惯的不用换算的计算方法：截面积*8.89=kg/km如120平方毫米计算：120*8.89=1066.8kg/km1。导体用量：（Kg/Km）=d^2*0.7854*G*N*K1*K2*C/d=铜线径G=铜比重N=条数K1=铜线绞入率K2=芯线绞入率C=绝缘芯线根数2。绝缘用量：（Kg/Km）=（D^2-d^2）*0.7854*G*C*K2D=绝缘外径d=导体外径G=绝缘比重K2=芯线绞入率C=绝缘芯线根数3。外被用量：（Kg/Km）=(D1^2-D^2)*0.7854*GD1=完成外径D=

2、上过程外径G=绝缘比重4。包带用量：（Kg/Km）=D^2*0.7854*t*G*ZD=上过程外径t=包带厚度G=包带比重Z=重叠率(1/4Lap=1.25)5。缠绕用量：（Kg/Km）=d^2*0.7854*G*N*Zd=铜线径N=条数G=比重Z=绞入率6。编织用量：（Kg/Km）=d^2*0.7854*T*N*G/cosθθ=atan(2*3.1416*(D+d*2))*目数/25.4/Td=编织铜线径T=锭数N=每锭条数G=铜比重比重：铜-8.89；银-10.50；铝-2.70；锌-7.05；镍-8.90；锡-7.30
